初始化ES备份设置

在S3存储上初始化ES备份设置，并在设置完成之后，进行一个创建快照操作

#!/bin/bash

ES_SNAPSHOT_TAG="auto"

CHECK_RESPONSE=$(curl -s -k -X POST "$ES_HOST/_snapshot/$ES_BACKUP_REPO_NAME/_verify?pretty" )
CHECKED_NODES=$(echo "$CHECK_RESPONSE" | jq -r '.nodes')


if [ "$CHECKED_NODES" == null ]; then
  echo "Doesn't exist an ES backup setting..."
  echo "A default backup setting will be generated. (using '$S3_CLIENT' s3 client and all backup files will be saved in a bucket : '$ES_BACKUP_BUCKET_IN_S3'"

  CREATE_ACKNOWLEDGED_FLAG=$(echo "$CREATE_RESPONSE" | jq -r '.acknowledged')

  if [ "$CREATE_ACKNOWLEDGED_FLAG" == true ]; then
    echo "Buckup setting '$ES_BACKUP_REPO_NAME' has been created successfully!"
  else
    echo "Failed to create backup setting '$ES_BACKUP_REPO_NAME', since $$CREATE_RESPONSE"
  fi
else
  echo "Already exist an ES backup setting '$ES_BACKUP_REPO_NAME'"
